Abstract: Effect of nitrogen treatments with three levels of nitrogen (0. 75, 1 . 5, 3 mol /L ) on the nutritionalquality of winter cress were studied. The results showed that the content of soluble sugar and soluble protein in leaves of two types of winter cress decreased significantly under the application of 3 mol /L nitrogen. The contents of glucosinolate of the leaves from P-type winter cress were not changed under the three levels application. Meanwhile, thecontent of total glucosinolates, aromatic glucosinolates and S-2-hydroxy-2-phenylethyl-glucosinolate in G-type wintercress leaves were inceased significantly under the application of 3 mol /L. The content of total glucosinolates, aromatic glucosinolates, R-2-hydroxy-2-phenylethyl-glucosinolate and 2-phenylethyl-glucosinolate in roots of P-type wintercress increased significantly under the 3 mol /L nitrogen, but the content of indol glucosinolates increased under the0. 75 mol /L nitrogen. However, the content of total glucosinolates, aromatic glucosinolates, indol glucosinolates andS-2-hydroxy-2-phenylethyl-glucosinolate in the roots of G-type winter cress decreased significantly under the 3mol /L nitrogen, but increased the content of 2-phenylethyl-glucosinolate.

Key words: Nitrogen, Barbarea vulgaris R. Br. , Soluble sugar, Soluble protein, Glucosinolate
